As far as I know there isn't anything based directly on that source material. Gurps is a system that is very moldable (name literally means Generic universal roleplaying system) and is great for that, but can also be overwheming at times. Gamma World has a post-apocalyptic setting but the tone is definitely off I think for something like the Martian Chronicles. Traveller also could be a fit though its always reminded me most strongly of Asimov's foundation series.

Actually, it's based more on H.G. Wells, Jules Verne, and A.C. Doyle, according to the Space 1889 rulebook, which Red Sands is a setting port of. It shows a healthy dose of Edgar Rice Borroughs, as well, especially in the Martians, but it makes no references to Bradbury that I am aware of. Also, Red Sands itself notes Wells, Verne, and Borroughs, not Bradbury. Bradbury isn't even mentioned in Red Sands.
